Keval Parekh

Backend Engineer — Java · Spring Boot · Microservices · Fintech

3+ years building production fintech backend systems. Primary author of authz-core, a shared Spring Boot authorization library deployed across 15+ microservices (Credit, Equity, Monitoring, EMS). Founding engineer of EMS — the entity management backbone of an AI-augmented private markets platform serving Blackstone, Bain Capital, Apollo, Hamilton Lane, and others.

What I Build

Authorization infrastructure authz-core: @AuthzPolicy declarative annotation model, JWT identity pipeline, UAM-backed product / role / entity validators. Published to Azure Artifacts as a versioned shared library; 85%+ test coverage; eliminated per-service auth duplication across 15+ microservices.

Multi-tenant fintech platforms Dynamic per-tenant data routing and schema isolation. Led migration of 17 enterprise PE/VC clients from legacy stack to EMS, preserving full entity-hierarchy and ownership integrity.

Bitemporal data systems As-of-date entity and relationship schemas enabling point-in-time reconstruction of investment hierarchies — supports audit, reporting, and regulatory queries.

Data integrity layers Cyclic-relationship graph detection and timeline-based ownership validation preventing cap-table corruption across securities and subscription workflows.
